the question I pose is are they true

If you insists then religions as something to practice are false. First of all, God cannot be experienced. None of our experiences can be labeled as, “Ah, that was true experience of God,” and “Ah, whatever this experience was, it was not experience of God.” All experiences are God experiencing God, but none can be pinpointed as the experience of God. There is simply no such thing. Even logically, if you could say such a thing, God could not be omnipresent (or what you experience/worship is some “lesser god”). Second, how does one practice union with oneself? It does not make sense, and religion as a ritualistic means to it is simply ridiculous (and the same is true for spirituality, but I guess you consider both religion and spirituality synonymous). All we can do is “rediscover” our divinity, and for that purpose religion, as we know it throughout the history, is more an impediment than a help. And again, if one denies one’s divinity (i.e. being through and through but God), how could God be omnipresent? And one last thing, Newtonian physics is still valid, it would become ridiculous only in the case if someone tried to base a whole world view on it and tried to fit Einstein’s relativity and quantum mechanics into its framework — basically it’s what religions try to do with science.
